air drill can be fitted with a variety of attachments for drilling
holes, grinding, polishing, and cleaning parts.
Air drills have the major advantage for automotive use that, unlike
an electric drill, they don't run the risk of producing sparks and
thereby igniting flammable liquids or gasoline tanks. They also
have no electric cable thath could be accidentally cut, causing
shock, nor do they get hot with heavy use. Some air drills have
a reversible action.
